Following on from this Meta TeX SE question, how about offering an SE-branded pastebin for posting long files? The problem with using things like pastebin is that files get deleted after some time. Since the idea of these sites is to build a repository of questions and answers, it's no good for our answers rely on broken links.
Ideally, "SE pastebin" would have the following features:
- Items not linked to by questions/answers on any SE site would be deleted.
- Users would be able to control when files expire (e.g. if you're posting output from
dmesgor the like, that can expire when you accept a solution, but if the text is, say, code used in the answer, then that should never expire).
- Users should be able to specify syntax highlighting.
